LISA Pathfinder exceeds all expectations, and begins the era of gravitational astronomy

LISA’s work is the result of many sacrifices that allow the beginning of the era of gravitational astronomy. Why that? LISA Pathfinder has gone through a long series of tests, implemented and corrected in order to exceeded all expectations, and it is with this result that the ESA work, the Italian Space Agency (ASI), the National Institute of Nuclear Physics (INFN) and the University of Trento has been awarded.

How Lorentz transformation improve the knowledge on space-time concept

Thanks to Lorentz transformation (name given by Henrì Poincarè) we have a theory that aim to give a scientific description of the change of viewpoint from one inertial frame to a second moving one. This specific change of viewpoint is called a (Lorentz) boost. Why Lorentz transformations are so important for human knowledge? His formulaeContinue reading “How Lorentz transformation improve the knowledge on space-time concept”
